Excel Motorcycle Booking System

I need a single Excel-based application that lets me run a small motorcycle fleet as smoothly as possible. The workbook should allow me to:

• Enter a reservation once and have the sheet immediately flag that motorcycle as unavailable for overlapping dates.
• Store every reservation in a permanent log that I can filter by bike, customer name, or date range, so I can review usage patterns or settle disputes later.

A clean front end (forms, drop-downs, or slicers) is important because different staff members will be using it each day. Behind the scenes you’re free to rely on formulas, tables, Power Query, or VBA—whatever delivers quick automatic availability updates and a reliable, searchable booking history without corrupting the data.

Acceptance criteria
– Adding or editing a reservation instantly refreshes availability for all motorcycles.
– The booking history keeps an untouchable audit trail; deleted or overwritten entries are impossible.
– File opens with macros enabled (or a macro-free alternative) on current versions of Excel for Windows and Mac.
– Clear instructions on adding new motorcycles or extending the calendar.

If you’ve built similar Excel scheduling tools before, feel free to share a short demo or screenshots so I can see the interface style.
